Robinson did not submit paperwork to the NFL draft advisory committee to find out what his draft grade might be. Instead, he relied on Crimson Tide coach Nick Saban, who used his sources to tell Robinson he was a mid to late first-round pick. VASHA HUNT, AP

With that in mind, here are five veterans whose spots with the Lions look a little more tenuous after the draft:

• LS Don Muhlbach: The Lions spent a sixth-round pick on long snapper Jimmy Landes, just the fifth time an NFL team has taken a true long snapper in the modern draft. General manager Bob Quinn said Landes and Muhlbach will compete for the job this fall, but teams don’t spend coveted draft picks on a specialist unless they intend for them to make the team. Muhlbach’s time in Detroit might be done after 12 seasons.

• QB Dan Orlovsky: Like Muhlbach, the Lions signed Orlovsky to a minimum salary benefit contract this off-season, then drafted someone at his position Saturday. Orlovsky provides plenty of value as a veteran sounding board for Matthew Stafford, something sixth-round pick Jake Rudock can’t match. Quinn said he doesn’t have a preference between keeping two or three quarterbacks, but his old team, the New England Patriots, rarely has carried three in recent years.

• OT Cornelius Lucas: After spending three draft picks on offensive linemen, the Lions suddenly look overcrowded at the tackle position. Some combination of Riley Reiff, Taylor Decker and Michael Ola will start at tackle, and fifth-round pick Joe Dahl looks seems a safe bet for a roster spot, given his versatility. With five players all but locked into the interior spots (Larry Warford, Travis Swanson, Laken Tomlinson, Geoff Schwartz and third-rounder Graham Glasgow) that leaves maybe one spot left for a lineman. Lucas has started games each of the last two seasons, but he’ll have to convince a new regime that he’s worth a spot while vying for backup reps with Lamar Holmes and Corey Robinson.

• C Travis Swanson: Swanson isn’t in the same position as the other four players, in that his spot on the 53-man roster isn’t in question. But the fact that the Lions spent a third-round pick on Glasgow can’t bode well for his future as starter. Swanson, a third-round pick himself in 2014, made 14 startsin an up-and-down 2015 season and missed time with a shoulder injury. His struggles weren’t as pronounced as some have made them out to be, but the offensive line coach who wanted him (Jeremiah Washburn) no longer is here. Glasgow can play both guard and center, while Swanson is considered a center only. The two look destined for a camp battle this fall.
